Perhaps you should try some spelling variations:
decrease lipid » increases lipid (Expand search), increased lipid (Expand search)
lipid decrease » rapid decrease (Expand search), ligand decrease (Expand search), limb decrease (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their objects » the objects (Expand search), their objectives (Expand search), their projects (Expand search)
decrease l » decrease il (Expand search), decrease _ (Expand search), decrease β (Expand search)
l decrease » _ decrease (Expand search), α decrease (Expand search), to decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lipid decrease l decrease ) OR ( decrease NOT decrease their objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lipid decrease l decrease ) OR ( decrease NOT decrease their objects ))*.
